How We Get Hot Water in Our Homes

There are a range of different ways we get hot water in our homes, each with their own benefits and drawbacks which make them perfect for some properties but not others. Here we explore six of the most common water heating methods for our homes.

System Boilers


Arguably the most traditionally common form of home water heating units; the system boiler is capable of storing a large volume of hot water, satisfying a high demand for heated water. The installation of the unit is quick and neat as all the components are built into the system boiler.
Unfortunately, some system boilers are prone to losing pressure over time and will run out of hot water if overused.

Combi Boilers


Providing instant hot water, combi boilers are hugely popular in new build homes and blocks of flats. Cheap and quick to install; combi boilers can help accommodate a busy lifestyle. The space-efficient boilers are capable of producing hot water through taps as well as hot water for heating through radiators and other heating units.


However, the traditionally small size of combi boilers means they are not particularly energy efficient due to the limited water storage they offer. Additionally, some combi boilers can struggle with numerous simultaneous open hot water taps.

Immersion Heater


The immersion is most commonly used in tandem with another water heating unit in the home as a back-up. Usually powered by electricity, the immersion heater contains a similar functionality to an electric kettle and can be very cheap to run.

Biomass Boilers


Growing in popularity throughout Scandinavia and in Austria, biomass boilers are principally fired with woodchips and wood pellets. The boilers are improving in functionality and simplicity of use, with units featuring auto-feed mechanisms and automatic ignitions. However, these units necessitate large amounts of space in which to operate, making them implausible for many homes and properties in the UK.

Heat Pump


Capable of operating in sub-zero conditions and requiring little maintenance, heat pumps extract heat from the outside ground or air for space and water heating functi­ona­liti­es. Best partnered with large storage tanks which do not require heating to incredibly high temperatures.
The main disadvantage of the heat pump is the inability in most units to deliver the highest temperature of water necessitated by most tasks. The heat pump is used most commonly for tasks such as under-floor heating which do not require such high water temperatures.

Solar Thermal


An envi­ron­men­tal­ly-efficient and wallet-friend form of energy; solar thermal heating relies on the power of the sun to heat a home’s water. A well planned and intelligently implemented solar thermal heating unit can halve your water heating bills but does rely on sufficient power produced by the sun. The size of the thermal panel unit required is dependent upon the number of people in the home and the subsequent hot water demand.
